From: Serge Mashtakov, PE

Date: 06 June, 2014

Re: KLWTD, Solar Power (Photo Voltaic) Array, Additional Information

As requested by the Board, the following additional information is provided for review.Based on the available information we are recommending to proceed with producing theRequest for Proposals (RFP) in which the technical and organizational specifics will be outlined.The recommendation is to incorporate in RFP selections criteria various factors of interestincluding: Total. Coast, Panel Efficiency, Manufacturer Warranty, Installation Warranty,Manufacturer Experience and references. Installation Contractor Experience and references,experience and references in South Florida, Service and Maintenance availability and otherfactors. Each evaluation factor will be assigned a weighted score so that the low bid is notnecessarily the winning bid.

The RFP will be presented to the Board for review and approval. The result of RFPprocess will produce contractually binding proposals from multiple licensed contractors. Basedon the review of the proposal by the staff and a staff recommendation of award, the Board willbe able to choose the most suitable option.

As part of the RFP, the proposer will be required to design all support systems for 200mph wind velocities and coastal exposure D. All frames and foundations will be specifiedutilizing low maintenance materials and techniques including heavy hot dip galvanized steelframes, stainless steel hardware, low corrosion reinforcement etc. Such approach will help toreduce O&M costs in the future and improve cost benefits of the system.

The chart available from NREL demonstrates updated efficiencycharacteristics fordifferent photovoltaic technologies and sub-technologies. For our application of on-land non-concentrator solar power, the most suitable technology is a Crystalline Silicone Cells (colorcoded BLUE). Other technologies are either not practical or not available for industrial use atthis time.

The SunPower cells, used is our preliminary assessment of the viabilityof solar power,are toppingthe efficiency listaccording to this graph. These more efficient cells not onlyproduce more electricity at the same sun light conditions (approximately +23%) but alsoextendthe time when the electricity can be produced during the low lightconditions (morning,evening, overcast)which adds another up to +8% of efficiency. Overall, the Crystalline SiliconeCell efficiencies can be as much as 30%greater than the lower efficiencycells. Due to thelimited amount of space available and practically no expansion potential for the District, It isrecommended to specify PhotovoltaicCell arrays with higher efficiencies in the RFP document.

3. PV Cell Arrays O&M

Since PV Cells don't have any moving parts and operate in low voltage range, the routineoperation and maintenance procedures are very limited. An occasional washing of panelsurfaces is needed in certain locations (proximityto dusty process, roads, bird nesting etc.).Quarterlyor biannual inspectionsof electrical connections and attachments of the panels tosupporting frames is a good practice.

The Real-Time monitoring systems are available from different manufacturers. Suchsystemsallow the owner to monitor ifany deviations in arrayefficiency haveoccurredindicating that maintenance is required. The output information of the monitoring system canbe made available to the public (on the District's web site) and can be monitored by the District.Thefollowing link provides an example of such a system installed inStock Island Marina Village:

https://www.sunpowermonitor.com/residential/kiosk.aspx?id=61063944-bdd8-48db-bd5f-cfbe236bb990

That array represents an example of higher efficiency panels used in Monroe County.The same panels are used by FPL in their large scale solar plants in DeSoto Countyand KennedySpace Center (see attached case study and articles).

Proposed Arrays for KLWTD will be relatively small and simple to maintain.Solarpanelsare normally sectioned in stringsof 10-12panels and inthe case of poor performance or failureof single a single panel the stringcan be easily isolated and limited number of them can then beinspected for defects or damage. Thermal Imaging equipment is commonly used to inspect and

Aiming to trim Florida's greenhouse gas emissions, in 2007 Florida Governor CharlieCrist announced a mandate for all of his state's utilities to generate at least 20 percent

of their power from renewable energy sources by 2020. Fortunately, for nearly threedecades the FPL Group- one of the nation's largest providers of electricity-relatedservices - had been exploring innovative energy technologies such as wind and solarpower, "We're a national leader in renewobles," notes Kathy Salvador, manger ofproject development at Florida Power & Light (FPL), one of the FPL Group's mainsubsidiaries. "So going to solar powered-eleclricity for our 4.4 million customerscomplements that strotegy."

SlJiMPOWizR I- . • Hv.-KJ;

As a state-regulated utility, FPL was required to have appropriate legislation in placeto produce solar power. Explains Salvador, "We needed a specific policy thatwouldallow us to recover the costs from our customers." By 2008 Florida lawmakers approvedsuch legislation, outhorizing the production of 110 megawatts of solar power statewide.In anticipation of the bill's passage FPL began evaluating solar providers, sending out aRequest for Information to approximately 50 vendors, and then asking for bids from a

short list of finalists. "Given the efficiency and cost of SunPower solar panels, their

experience with utility-scale projects, and the fact that they could commit to deliveringwithin our timeframe, SunPower was the obvious choice," Salvador says.

hi: Mi: i-l i i-jf • •,'/ •. :-;ij : M • - Uk •

SunPower constructed two ground-mounted solar installations for FPL. Thefirst, a

180-acre, 25MW facility now called the DeSoto NextGeneration Solor Energy Center,was completed in record time, with a price tog that earned FPL's acclaim. "If took lessthan a year, we finished ahead of schedule, and we came in $22 million under budget,"Salvador reports (the second, 1OMW facility at NASA's Kennedy Space Center, also

was online before its targeted completion dote). DeSoto County's economy received asignificant boost from the project, Salvador adds. "We created 400 construction jobs,

and our county - which is a poor one - will receive millions of dollars in taxes, whichwill help strengthen our infrastructure." In early 2010, legislation was being proposedto expand Florida's solar power production to 700 megawatts over the next three years.

"When that passes," Salvador predicts, "we'll be ready."

FPL, NASA celebrate new solar array at Kennedy Space Center

CAPE CANAVERAL, Fla. - AtKennedy Space Center today. Sen. B1Nelson and Reps. Suzanne Kosmas and Bill Poseyjoined oflBciais from Florida Power& Li^t ConpanyandNASA tox:elebrate thegroundbreaking ofFPL's Space Coast Next GenerationSolar EnergyCenter.

The new solar photovoltaic power fecility is the result ofa unique public-private pannership between FPL and NASA and demonstrates both organizations'commitment to bringmg clean-energy solutions to thestate.

"The Space Coast Next Generation Solar Energy Center is aninportant part ofFlorida's clean-energy future. 1grew up in Florida, seeing NASA asthe home ofhistoric American achievements, so I love the idea ofFPLhelping to power the space program," said FPL President and CEO Armando J.Olivera. "Like NASA,FPLis looking beyond the horizon. Weare building more emissions-free solar power with the quality oflife ofourchildren and grandchildren inmind."

'Thepartnershp between NASA and FPL isanexcellent one that comes at the right time," said Robert Cabana, director ofKennedy Space Center. "Itwill he^provide clean, renewable power toFlorida residents, itwill help sipport America's space program bysupplying electricity directly toKennedy Space Center, andithelpsto reduceour reliance on fossil fiiels and improves theenvironment."

The Space Coast NextGeneration Solar Energy Center will be located onNASA property at Kennedy Space Center and, when completed, will produce anestimated 10ihegawatts ofclean, emissions-free powerfor FPLcustomers, which isenough energy toserve roughs 1,100 homes.

FPLisalso building a separate solarfecility ofapproximate^ onemegawatt thatwill provide clean power directly to Kennedy SpaceCenter, hewing NASAmeetits renewableenergygoals.

"There's nobettertime than right nowto startusing thesunandotherclean soiacesto powerAmerica," saidNelsoa "And, perhaps, there's nobetteragency tohe^ lead the waythan NASA. Let'shope powercompanies all overthecountry takea cue from this partnership."

"Florida is poised tobea leader inAmerica's growing clean energy econony, which naturally includes solar power,!' said Kosmas. "Bringing new clean energyjobstoourcommunities is oneofmy toppriorities. This joint effort between NASA andFPLisanexanple ofhow wecancreate jobswhile investing incommon-sense solutions to the economic, environmental and natbnal securitychallenges we fece today."

"As a member ofthe Congressional Renewable Energy Caucus, I have a strong commitment torenewable energy and ampleased toseethis project going forwardright here onthe Space Coast," said Posey. "This isaninportant stepin the development offuture sources ofrenewable energy and isone way wecanreverse ourdependenceon foreign oil"

The Space Coast NextGeneratbn Solar Energy Center will reduce carbon dioxide emissions bymore than 227,000 tons, which isthe equivalent ofremoving1,800 cars off"the road each yearaccording to the U.S. Environmental Protectron Agency. Itwill also save approximately 122,000 barrels ofoil and 2.8 billioncubic feetofnaturalgas over its lifetime.

Additional^, the solar array will provide about 100 jobsduring construction, helping to boost the local economy in Brevrmd County. FPLexpects to complete theproject by the"middle ofnextyear at the latest.

The fecility will feature approximatefy 35,000 highty efficient solar photovoltaic panels from SunPower, a global leader incommercial-scale solar power technology,across 60acres at Kennedy Space Center. The panels are50 percent more powerful than conventional solar panels. Last month, SunPower andFPLGrovq)announced a svgjply agreement beginning in 2010 throu^2012. SunPower has also committed tolocating a research and development center in Florida ifthe statecontinues its robust solar program

The Space Coast Next Generation Solar Energy Center is one ofthree solar facilities that FPLis currently building in the state ofFlorida, totaling 110 megawatts ofclean, renewable energy generation. TheMartin NextGeneration SolarEnergy Center inIndiantown will be the world's first hybrid solar thermal facility to connecttoanexisting fossil fuel plant It isthelargest of the three at75 megawatts andisscheduled to be conplete in 2010. FPL'scontractor onthe project LaurenConstruction & Engineers, iscurrentfy hiring about1,000 workers to corrplete thework.

FPL'sDeSoto NextGeneration SolarEnergy Center, a 25-megawatt solarphotovoltaic facility inArcadia, will be thenation's largest photovoltaic arraywhen it isconplete later this year. Theprojecthasbrought morethan 200 construction jobs to DeSotoCounty.

NREL Learning - Solar Photovoltaic TechnologyBasics

Solar Photovoltaic Technology BasicsSolar cells, also called photovoltaic(PV) cells by scientists, convertsunlight directly into electricity. PVgets its name from the process ofconverting light (photons) to electricity(voltage), which is called the /Veffect. The PV effect was discovered

in 1954, when scientists at BellTelephone discovered that silicon (anelement found in sand) created anelectric charge when exposed tosunlight, Soon solar cells were beingused to power space satellites andsmaller items like calculators and

watches. Today, thousands of peoplepower their homes and businesses withindividual solar PV systems. Utilitycompanies are also using PVtechnology for large power stations.

Solar panels used to power homes andbusinesses are typically made fromsolar cells combined into modules that

hold about 40 cells. A typical home willuse about 10 to 20 solar panels to power the home. The panels are mounted at a fixedangle facing south, or they can be mounted on a tracking device that follows the sun,allowing them to capture the most sunlight. Many solar panels corrbined together tocreate one system is called a solar array. For large electric utility or industrialapplications, hundreds of solar arrays are interconnected to fonm a large utility-scale PVsystem.

Traditional solar cells are made from silicon, areusually flat-plate, and generally are the mostefficient. Second-generation solar cells are calledthin-film solar cells because they are made fromamorphous silicon or nonsilicon materials such ascadrrium tellurlde. Thin film solar cells use layers ofsemiconductor materials only a few micrometersthick. Because of their flexibility, thin film solar cellscan double as rooftop shingles and tiles, buildingfacades, or the glazing for skylights.

Third-generation solar celts are being made fromvariety of new materials besides silicon, includingsolar inks using conventional printing presstechnologies, solar dyes, and conductive plastics,Some new solar cells use plastic lenses or m'rrorsto concentrate sunlight onto a very small piece ofhigh efficiency PV rrBteriai. The PV material is moreexpensive, but because so little is needed, thesesystems are becoming cost effective for use byutilities and industry, However, because the lensesmust be pointed at the sun, the use ofconcentrating collectors is limited to the sunniestparts of the country.

Most Efficient Soiar Panels — Which Ones?

One of the most common things people ask when they start to consider going solar or start to plan their life-changing solar expedition is

which are the most efficient solar panels. However, first of all, that's not even the right question for most people, and second of all, the

literal answer to that question really isn't relevant for the average consumer. Let me explain....

First of all, the important matter is not which solar panels are most efficient, but which solar panels are the best value for the money. If

you've got space for 10 solar panels on your roof and you have an option between solar panels "ABEfficient" that are a bit more efficient

but twice the price of solar panels "CDCheap," chances are, you are going to make a much bigger savings by going with CDCheap. Of

course, the important thing would be to see what's available in your situation and simply run the numbers (or, if you are allergic to math,

have a friend who can do math run the numbers for you).

But, anyway, if you really want to know which are the most efficient solar panels (or solar cells) out there, I actually happened to be

putting together a list of solar records recently and can give you the rundown. But, as I do so, I'll drop In a few key notes making the

point above a bit clearer. Before looking at solar panels as a whole, let's have a quick look at the producers of some of the most efficient

solar cells (the key component of solar panels) and their efficiency records;

• 44.4% efficient solar cells by Sharp fhttp;//5Qlarlove.org/sharp-solar-cetl-efficiencV'record-another'One-444/). Notably,these world-leading solar cells by Sharp are in the concentrator triple-junction solar cell category. Such solar cells are complicatedand are not used in residential or commercial applications... because they are bloody expensive. They are used In spaceapplications by the likes of NASA, where a bit of extra space (or, as It may be, less space via extra efficiency) can make a hugedifference.

• 37.9% efficient solar ceHs by Sharp (http://solarlove.org/sharp-regains-solar-cell'efflciencv-record/). lust a step down,these are in the triple-junction, non-concentrator solar cell category. If this is all new to you, it might take you awhile to see thedifference in the categories. The difference is that these solar cells don't use anything to concentrate the light hitting the solarcells, while the 44.4% efficiency cells above do use something to concentrate the light (of course, adding to their costs).

• 32.6% solar cells by a Spanish solar research institute flESI and university fUPM)fhttp5://upload.wikimedia.org/wikipedia/commons/a/aa/PVeff%28rev130621%29.|pgT These are another step down, as theyare in the two-junction, concentrator solar cell category. (For an intro on "junctions," by the way, check out this multi-iunctionohotovoltaic cell article (httD://en.wikiDedia.org/wiki/Multijunction photovoltaic cell) on Wikipedia.) Again, these are still fardifferent solar cells from what are used in commercial or residential installations.

• There are about a dozen or so extra categories that I could run down. Some categories have very high efficiencies but the solarcells are quite expensive) while others are actually on the other end of the spectrum (no pun Intended) and are very cheap buthave very low efficiency. Of course, some are both inefficient and expensive, but apparently worth researching nonetheless. Thekey, as I noted earlier, is finding the best balance between cost and efficiency.

Now,there's.less research on solar panels than on solar cells because the core of the technology Is the solar cell, sothafs what

researchers at many Institutes and universities spend their time on. No one Is even going to try to manufacture a solar panel that won't

sell because it isn't made of marketable solar cells. Still, there are many different types of soiar panels (more accurately known as solar

modules) on the market and many, many manufacturers of some of the most common types. So let's look at the leaders in this category.

Why didn't I start with the solar modules? Because then it would be easier to miss the point,which is that solar panel efficiency is not

the metric you use to choose solar panels for you home. Getting on to the solar modules, here are the most efficient solar modules

in a few key categories:

• 36% efficient Amonix solar modules fhttp://solarlove.org/amonix-achieves-worlcl-record-for-pv-moclule-efficiency-in-test-at-nrel/1 hold the overall solar PV module efficiency record. However, these are made with concentrator solar cells and are notused in residential applications.

• 21.5% SunPower solar modules (http://solarlove.orp/sunpower-launches-commercial'Solar'PanelS'With-world-recorcl-efficiencY'X-series/) hold the commercial solar module efficiency record. SunPower's SPR-327NE-WHT-D modulesfhttp://cleantechnica.com/2013/04/08/world-record-x-series-solar-panels-no-for-sale/} are also the leading solar modules in solar

module yield field tests, and other SunPower solar modules come in #2 and #3 in those tests. (For those of you to who this mattersor is interesting, SunPower is a US-based solar panel company.)

• 17.4% O-Cells thin-film solar modules fhttp://clcantechnica.com/2011/12/05/new-thin-film-solar-modulc-cfficiency-record-set/I hold the record in this specific solar panel category. Thin-film solar panels are widely used, but not in residentialapplications. (Q-Cells was a German company, but it filed for insolvency in 2012 and was then acquired by the Koreancompany Hanwha.)

• 16.1% First Solar thin-film solar modules fhttp;//cleantechnica.com/2013/04/10/first-solar-stock-surges-on-3-big'announcements/1 claim the cadmium-telluride (CdTe) photovoltaic (PV) module conversion efficiency record. Again, these aregenerally not used for residential applications, but I think including them helps to reinforce my key point yet again. (First Solar, aUS-based company, was actually the #1 solar developer and the #2 solar module manufacturer in the world last year. Despite arelatively low 16.1% record efficiency in this category of solar panels, First Solar does very well with these relatively cheap solarmodules in certain applications.)

• Just as one final example in order to show that the variation doesn't stop there, 15.5% solar modules from MiaSol6fhttp;//cleantechnica.com/2012/05/25/miasol-sets-new-world-record-flexible-pv-module-efficiency/l hold the flexible PVsolar module efficiency record. Naturally, in some applications, one doesn't just need solar panels, one needs flexible solar panels.But, that probably isn't you....fhttp://cleantechnica.com/2012/05/25/miasol-sets-new-world-record-flexible-pv-module-efficiency/1

The takeaway point is:

Skip the focus on hypothetlcais and Irrelevant superlatives. Forget about what the "most efficient solar panels" are. Check on

the solar Installers in your area (you can get connected to them via our home page fhttp://costofsolar.com/ll. See what they

quote you. Ask them what solar panels they would use if you want to know. And compare your options to your heart's content. Don't go

trying to find solar panels that were designed for NASA satellites.

Bythe way, the following chart from NREL (http://www.nrel.g0v/l isn't fully up to date (solar efficiency records are broken quite

frequently), but it gives you a good sense of the large variety of solar technologies:

Solar: Summary

Solar electricity generating capacity grew by a factor of over 21 between 2000

and 2012 and currently accounts for 0.3% of annual U.S. electricity generation,

Countries with extensive solar policies—such as Gernnany, Spain, and Italy-

lead the world in solar photovoltaic (PV) deployment. Similarly, U,S, states with

extensive solar incentives lead the United States in both cumulative and

annual Installations in 2012 (California, Arizona, New Jersey. Nevada, and Colorado).

U.S. manufacturers currently have a small share of the worldwide PV market.

Asian—particularly Chinese—manufacturers lead the market with nearly 85%

of the global photovoltaic module production.

30 MW of new concentrating solar power (CSP) capacity came online in the United

States in 2012. Approximately 1.6 GW of CSP projects are currently under

construction in the United States and are projected to come online in 2013 and

2014; 900 MW are estimated to come online in 2013 alone.
